Abstract: Chickpea (Cicer arietinum L.) is an important food legume crop, particularly for the arid regions newlineincluding Indian subcontinent, providing one of the most balanced nutritional compositions. newlineChickpea is a valuable source for many important proteins, mineral and vitamins among legumes newlineand contributes a major protein component to the predominantly vegetarian diet in India. newlineEcologically, chickpea is also known as an efficient N2-fixing system due to its capability of newlinesymbiotic nitrogen fixation (SNF). Annual chickpea production in India remained 7.06 million newlinetonnes (MT) for the year 2009, with an average yield of 0.89 t/ha. India ranks number 1 in global newlinechickpea production but ranks 31st in average yield. Current global yield average of chickpea is newline0.9 t/ha, which is very much less than estimated potential of 6 t/ha under optimum growing newlineconditions. Despite its economic importance chickpea productivity/yield is significantly low as newlinecompared to expected because of losses due to various abiotic (drought, cold and salinity) and newlinebiotic stresses (Helicoverpa, Ascochyta blight, Fusarium wilt and Botrytis grey mold). newline newlineThe work embodied in this thesis describes the identification of ten abiotic stress newlineresponsive candidate genes based on sequence similarity approach, which have been previously newlineproved to play an important role in abiotic stress response in known model crops and map those newlinegenes with abiotic stress responsive traits. These candidate genes were then used for allele newlinemining and detection of marker trait association with abiotic stress related root traits, using newlinediversity available in chickpea mini core collection using candidate gene based association newlinemapping.
